Hi all,
I've just installed an fse boost valve to my pug 306 1.8 16V. Now every time I turn the ignition on a high pitched whistle occurs that comes from the fuel pressure regulator. As if its pressurising up. What's more when I accelerate hard a sustained whistle can be heard. Funny thing is it doesn't occur on cold mornings 13 degrees C but then reoccurs when I drive home from work in the afternoon 18 degrees C. Could this be a temperature related problem or is there an underlying fault?
